Answer:
Yeah its 7 because when you add 3+2=5, and x is 2, its 7
(I'm learning this right now!)
y = 3x - 3
If a line is perpendicular to another line, they have negative reciprocal slopes.
So you would use the slope -1/3.
Use y - y₁ = m(x - x₁) to get an equation in slope intercept form.
Plug the numbers in.
y - 1 = -1/3(x - 3)
y - 1 = -1/3x + 1
y = -1/3x + 2
An equation of a line perpendicular to line CD is y = -1/3x + 2.
Answer:
The slope is 4, and the y-intercept is Negative five-halves
Step-by-step explanation:
we have

This is the equation of the line in standard form
Convert the equation in slope intercept form

where
m is the slope
b is the y-intercept
Isolate the variable y
Subtract 8x both sides

Divide by -2 both sides

therefore

128 square inches.
The area of a triangle is 1/2bh, where b is the base and h is the height. Substitute the values in.
1/2 * 8 * 32
Now, just solve.
4 * 32
128 square inches
